120 patients scheduled for VPS surgery were randomised for laparoscopic or open insertion of the peritoneal catheter. The primary endpoint was the rate of overall shunt complication/failure after 12 months. Secondary endpoints were distal shunt failure rate at 6 weeks, 6 months and 12 months, overall complication/failure at 6 weeks and 6 months, duration of surgery and hospitalisation, and morbidity.
